LAN interface keeps being detected as WAN interface

RouterOS
1

Hi everyone,
I’ve added vlan3 to my LAN interface list and also excluded LAN from the WAN interface list.
However, each time the router still detects vlan3 as a WAN interface dynamically — even though it’s already assigned to the LAN list.

Does anyone know why this happens or how I can stop VLAN3 from being detected as WAN?

As people have been told many times on this forum: You should not use the "Detect Internet" features. It's buggy and is known to cause many unwanted problems. Set all lists to none and forget that it exists.
